FIELD OF DISCLOSURE

The present disclosure is directed to inhibitors of the CBP/p300 family of bromodomains useful in the treatment of disease or disorders associated with the inhibition of the CBP/p300 family of bromodomains. Specifically, the disclosure is concerned with compounds and compositions for inhibition of the CBP/p300 family of bromodomains, methods of treating, preventing, or ameliorating diseases or disorders associated with the inhibition of CBP/p300 family of bromodomains, and methods of synthesis of these compounds.

BACKGROUND OF DISCLOSURE

p300 (also known as EP300 and KAT3B) is a large protein with multiple domains that bind to diverse proteins including many DNA-binding transcription factors. The cyclic AMP-responsive element-binding protein (CREB) binding protein (CBP, also known as KAT3A) is a cellular paralog of p300. p300 and CBP share extensive sequence identity and functional similarity. As such, they are often referred to as CBP/p300 in the scientific literature. CBP/p300 are lysine acetyltransferases that catalyze the attachment of an acetyl group to a lysine side chain of histones and other protein substrates. As large proteins, CBP/p300 were proposed to activate transcription in part by bridging DNA-binding transcription factors to RNA polymerase machinery or by helping assemble the transcriptional pre-initiation complex (PIC). Importantly, CBP/p300-catalyzed acetylation of histones and other proteins is pivotal to gene activation. Heightened p300 expression and activities have been observed in advanced human cancers such as prostate and liver (cancer and appear to be associated with poor prognosis of these cancer types. Compared to normal tissue counterparts, the expression levels of p300 are higher in human primary breast cancer specimens and in mouse mammary carcinomas induced by polyomavirus middle-T oncogene.

Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other. Compounds containing multiple stereogenic centers with different relative configurations are considered to be diastereomers. The term “diastereomer” refers to any member of this set of compounds. In some examples presented, the synthetic route may produce a single diastereomer or a mixture of diastereomers. In some cases these diastereomers were separated and in other cases a wavy bond is used to indicate the structural element where configuration is variable.

An “effective amount” when used in connection with a compound is an amount effective for treating or preventing a disease in a subject as described herein.

The term “carrier”, as used in this disclosure, encompasses carriers, excipients, and diluents and means a material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material, involved in carrying or transporting a pharmaceutical agent from one organ, or portion of the body, to another organ, or portion of the body of a subject.

The term “treating” with regard to a subject, refers to improving at least one symptom of the subject's disorder. Treating includes curing, improving, or at least partially ameliorating the disorder.

The term “disorder” is used in this disclosure to mean, and is used interchangeably with, the terms disease, condition, or illness, unless otherwise indicated.

The term “administer”, “administering”, or “administration” as used in this disclosure refers to either directly administering a disclosed compound or pharmaceutically acceptable salt of the disclosed compound or a composition to a subject, or administering a prodrug derivative or analog of the compound or pharmaceutically acceptable salt of the compound or composition to the subject, which can form an equivalent amount of active compound within the subject's body.

A “patient” or “subject” is a mammal, e.g., a human, mouse, rat, guinea pig, dog, cat, horse, cow, pig, or non-human primate, such as a monkey, chimpanzee, baboon or rhesus.

It should be understood that all isomeric forms are included within the present disclosure, including mixtures thereof. If the compound contains a double bond, the substituent may be in the E or Z configuration. If the compound contains a disubstituted cycloalkyl, the cycloalkyl substituent may have a cis- or trans configuration. All tautomeric forms are also intended to be included.

Compounds of Formula (I), and salts, solvates, esters and prodrugs thereof, may exist in their tautomeric form (for example, as an amide or imino ether). All such tautomeric forms are contemplated herein as part of the present disclosure.

The compounds of Formula (I), may contain asymmetric or chiral centers, and, therefore, exist in different stereoisomeric forms. It is intended that all stereoisomeric forms of the compounds of Formula (I) as well as mixtures thereof, including racemic mixtures, form part of the present disclosure. In addition, the present disclosure embraces all geometric and positional isomers. For example, if a compound of Formula (I), incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the disclosure. Each compound herein disclosed includes all the enantiomers that conform to the general structure of the compound. The compounds may be in a racemic or enantiomerically pure form, or any other form in terms of stereochemistry. The assay results may reflect the data collected for the racemic form, the enantiomerically pure form, or any other form in terms of stereochemistry.

Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some of the compounds of Formula (I) may be atropisomers (e.g., substituted biaryls) and are considered as part of this disclosure. Enantiomers can also be separated by use of a chiral HPLC column.

It is also possible that the compounds of Formula (I), may exist in different tautomeric forms, and all such forms are embraced within the scope of the disclosure. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the disclosure.

All stereoisomers (for example, geometric isomers, optical isomers and the like) of the present compounds (including those of the salts, solvates, esters and prodrugs of the compounds as well as the salts, solvates and esters of the prodrugs), such as those which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, and diastereomeric forms, are contemplated within the scope of this disclosure, as are positional isomers (such as, for example, 4-pyridyl and 3-pyridyl). (For example, if a compound of Formula (I) incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the disclosure. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the disclosure.) Individual stereoisomers of the compounds of the disclosure may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present disclosure can have the S or R configuration as defined by the IUPAC 1974 Recommendations. The use of the terms “salt”, “solvate”, “ester,” “prodrug” and the like, is intended to equally apply to the salt, solvate, ester and prodrug of enantiomers, stereoisomers, rotamers, tautomers, positional isomers, racemates or prodrugs of the inventive compounds.

The present disclosure also embraces isotopically-labelled compounds of the present disclosure which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine and chlorine, such as ²H (or D), ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl, respectively.

Certain isotopically-labelled compounds of Formula (I) (e.g., those labeled with ³H and ¹⁴C) are useful in compound and/or substrate tissue distribution assays. Tritiated (i.e., ³H) and carbon-14 (i.e., ⁴C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labelled compounds of Formula (I) can generally be prepared by following procedures analogous to those disclosed in the Schemes and/or in the Examples herein below, by substituting an appropriate isotopically labelled reagent for a non-isotopically labelled reagent.

The compounds of Formula (I) may form salts which are also within the scope of this disclosure. Reference to a compound of the Formula (I) herein is understood to include reference to salts thereof, unless otherwise indicated.

The present disclosure relates to compounds which are modulators of one or more bromodomains of the CBP/p300 family. In one embodiment, the compounds of the present disclosure are inhibitors of one or more bromodomains of the CBP/p300 family.

Step 1. Synthesis of methyl (2S)-5-amino-6-([7-[(tert-butoxy)carbonyl]-7-azaspiro [3.5]nonan-1-yl]amino)-2-methyl-1,2,3,4-tetrahydroquinoline-1-carboxylate

Into a 10-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, methyl (2 S)-5-amino-6-bromo-2-methyl-1,2,3,4-tetrahydroquinoline-1-carboxylate (100 mg, 0.33 mmol, Intermediate 1) was dissolved in toluene (4 mL). Then tert-butyl 1-amino-7-azaspiro[3.5]nonane-7-carboxylate (242 mg, 1.01 mmol), Brettphos (36 mg, 0.07 mmol), 3rd Generation BrettPhos precatalyst (60.8 mg, 0.07 mmol) and sodium tert-butoxide (48.3 mg, 0.50 mmol) were added. The resulting solution was stirred for 1 h at 100° C. under nitrogen atmosphere. The reaction mixture was cooled to room temperature and the solids were filtered out. The filtrate was concentrated under vacuum. The residue was subjected to purification by FCC eluting with ethyl acetate/petroleum ether (2:1). This afforded the title compound (52.8 mg, 34%) as a brown solid. MS: (ES, m/z): 459 [M+H]⁺.

Step 2. Synthesis of tert-butyl 1-[(7S)-2-benzyl-6-(methoxycarbonyl)-7-methyl-3H,6H,7H,8H,9H-imidazo[4,5-f]quinolin-3-yl]-7-azaspiro[3.5]nonane-7-carboxylate

Into a 25-mL round-bottom flask, methyl (2S)-5-amino-6-([7-[(tert-butoxy)carbonyl]-7-azaspiro[3.5]nonan-1-yl]amino)-2-methyl-1,2,3,4-tetrahydroquinoline-1-carboxylate (52.8 mg, 0.12 mmol) was dissolved in dichloromethane (5 mL). Then 2-phenylacetaldehyde (83 mg, 0.69 mmol) was added. The resulting solution was stirred for 4 h at room temperature. The resulting mixture was concentrated under vacuum. The residue was subjected to purification by FCC eluting with ethyl acetate/petroleum ether (2:1). This afforded the title compound (25 mg, 39%) as a yellow oil. MS: (ES, m/z): 559 [M+H]⁺.

Step 3. Synthesis of methyl (S)-2-benzyl-7-methyl-3-((S)-7-azaspiro[3.5]nonan-1-yl)-3,7,8,9-tetrahydro-6H-imidazo[4,5-f]quinoline-6-carboxylate and methyl (S)-2-benzyl-7-methyl-3-((R)-7-azaspiro [3.5]nonan-1-yl)-3,7,8,9-tetrahydro-6H-imidazo[4,5-f]quinoline-6-carboxylate

Example 217: methyl (S)-2-benzyl-3-(2-(1,1-dioxidothiomorpholino)ethyl)-7-methyl-3,7,8,9-tetrahydro-6H-imidazo[4,5-f]quinoline-6-carboxylate

Step 1. Synthesis of methyl (2S)-5-amino-6-[(2,2-dimethoxyethyl)amino]-2-methyl-1,2,3,4-tetrahydroquinoline-1-carboxylate

Into a 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, methyl (2 S)-5-amino-6-bromo-2-methyl-1,2,3,4-tetrahydroquinoline-1-carboxylate (500 mg, 1.67 mmol, Intermediate 1) was dissolved in toluene (10 mL). Then 2,2-dimethoxyethan-1-amine (1.09 g, 10.37 mmol), sodium tert-butoxide (480 mg, 4.99 mmol), 3rd Generation BrettPhos precatalyst (150 mg, 0.17 mmol) and BrettPhos (180 mg, 0.34 mmo) were added successively. The resulting solution was stirred for 2 h at 110° C. under nitrogen atmosphere. The reaction mixture was cooled and the resulting solids were filtered out. The filtrate was concentrated under vacuum. The residue was subjected to purification by FCC eluting with ethyl acetate/petroleum ether (3:1). This afforded the title compound (530 mg, 98%) as a brown oil. MS: (ES, m/z): 324 [M+H]⁺.

Step 2. Synthesis of methyl (7S)-2-benzyl-3-(2,2-dimethoxyethyl)-7-methyl-3H,6H,7H,8H,9H-imidazo[4,5-f]quinoline-6-carboxylate

Into a 100-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen, methyl (2 S)-5-amino-6-[(2,2-dimethoxyethyl)amino]-2-methyl-1,2,3,4-tetrahydroquinoline-1-carboxylate (530 mg, 1.64 mmol) was dissolved in toluene (15 mL). Then 2-phenylacetaldehyde (423 mg, 3.52 mmol) was added. The resulting solution was stirred for 14 h at room temperature. The resulting mixture was concentrated under vacuum. The residue was subjected to purification by FCC eluting with ethyl acetate/petroleum ether (1:1). This afforded the title compound (520 mg, 75%) as a yellow oil. MS: (ES, m/z): 424 [M+H]⁺.

Step 3. Synthesis of methyl (7S)-2-benzyl-7-methyl-3-(2-oxoethyl)-3H,6H,7H,8H,9H-imidazo[4,5-f]quinoline-6-carboxylate

Into a 100-mL round-bottom flask, methyl (7S)-2-benzyl-3-(2,2-dimethoxyethyl)-7-methyl-3H,6H,7H,8H,9H-imidazo[4,5-f]quinoline-6-carboxylate (520 mg, 1.23 mmol) was dissolved in tetrahydrofuran (4 mL). Then hydrochloric acid (4 M, 8 mL) was added. The resulting solution was stirred for 3 h at 60° C. The reaction mixture was cooled to room temperature. The resulting solution was diluted with 40 mL of water and extracted with 2×90 mL of ethyl acetate and the organic layers were combined, dried over anhydrous sodium sulfate, filtered and concentrated under vacuum. This afforded the title compound (450 mg, crude) as a yellow solid. MS: (ES, m/z): 396 [M+H₂O]⁺.

Step 4. Synthesis of methyl (S)-2-benzyl-3-(2-(1,1-dioxidothiomorpholino)ethyl)-7-methyl-3,7,8,9-tetrahydro-6H-imidazo[4,5-f]quinoline-6-carboxylate

Into a 50-mL round-bottom flask, methyl (7S)-2-benzyl-7-methyl-3-(2-oxoethyl)-3H,6H,7H,8H,9H-imidazo[4,5-f]quinoline-6-carboxylate (80 mg, 0.21 mmol) was dissolved in methanol (6 mL). Then thiomorpholine 1,1-dioxide (143 mg, 1.06 mmol) and acetic acid (127 mg, 2.11 mmol) were added. The mixture was stirred at room temperature for 30 min. To the mixture was added sodium cyanoborohydride (134 mg, 2.13 mmol) at 0° C. The resulting solution was stirred for 12 h at room temperature. Then water (20 mL) was added slowly. The resulting solution was extracted with 2×60 mL of ethyl acetate. The organic layers were combined, dried over anhydrous sodium sulfate, filtered and concentrated under vacuum. The crude product was purified by Prep-HPLC with the following conditions: Column, XBridge C18 OBD Prep Column, 100 Å, 5 μm, 19 mm×250 mm; mobile phase, A: water (containing 10 mmol/L NH₄HCO₃) and B: ACN (25.0% to 40.0% ACN over 10 min); UV Detector: 254 nm. This afforded the title compound (31 mg, 29%) as a white solid.

Example 963: HTRF Biochemical Assay for CBP and BRD4 Activity

The assay was performed in a final volume of 6 μL in assay buffer containing 50 mM Hepes (pH 7.5, (0.5M Hepes, pH 7.5 solution; Teknova H1575)), 0.5 mM GSH, 0.01% BGG (0.22 μM filtered, Sigma, G7516-25G), 0.005% BSA (0.22 μM filtered, EMD Millipore Cosporation, 126575) and 0.01% Triton X-100 (Sigma, T9284-10L). Nanoliter quantities of 10-point, 3-fold serial dilution in DMSO were pre-dispensed into 1536 assay plates (Corning, #3724BC) for a final test concentration of 33 μM to 1.7 nM, top to lowest dose, respectively. 3 of 2× Protein and 3 μL of 2× Peptide Ligand were added to assay plates (pre-stamped with compound). Plates were incubated for varying times at room temperature prior to measuring the signal. TR-FRET (Time-Resolved Fluorescence Resonance Energy Transfer) was measured on the PHERAstar (BMG, equipped with HTRF optic module [337/520/490]) or on the Envision (PerkinElmer, equipped with the TRF Laser unit, TRF dual mirror D400/D505 and emission filters M520 and M495). Data were reported as percent inhibition compared with control wells based on the following equation: % inh=1−((TR-FRET ratio−AveLow)/(AveHigh−AveLow)) where TR-FRET ratio=(Fluorescence at 520 nm/Fluorescence at 490 nm)*10000), AveLow=average TR-FRET ratio of no enzyme control (n=32), and AveHigh=average TR-FRET ratio of DMSO control (n=32). IC50 values were determined by curve fitting of the standard 4 parameter logistic fitting algorithm included in the Activity Base software package: IDBS XE Designer Model 205. Data is fitted using the Levenburg Marquardt algorithm. For all assay formats data were reported as percent inhibition compared with control wells based on the following equation: % inh=100*((FLU−AveLow)/(AveHigh−AveLow)) where FLU=measured Fluorescence, AveLow=average Fluorescence of no enzyme control (n=32), and AveHigh=average Fluorescence of DMSO control (n=32). IC50 values were determined by curve fitting of the standard 4 parameter logistic fitting algorithm included in the Activity Base software package: IDBS XE Designer Model 205. Data is fitted using the Levenburg Marquardt algorithm. IC₅₀ values are shown in Table 19, below. As set forth in Table 19 below, an IC₅₀ value of greater than or equal to 0.001 μM and less than or equal to 0.01 μM is marked “++++”; a value greater than 0.01 μM and less than or equal to 0.1 μM is marked “+++”; a value greater than 0.1 μM and less than or equal to 1 μM is marked “++”; and a value greater than 1 μM and less than 1000 μM is marked “+.” Compounds that were not tested in a particular assay are marked “NT.”
